To all whom it may cof/wem:

Be it known that I, HENRY SPENCER BLAcirMonn, a citizen of the United States, residing at Mount Vernon, in the count f of l-Vestchester and State of New York, iave invented certain new and useful Improvements in Processes of Making Ammonia,

' Alkyl Ammonia, or Ammonia Bases, of

which the following is a specification. Y

The obgect of this invention 1s to produce ammonia, alkyl-ammonia or ammonia bases,

and consists in uniting or combining nitroalnity for ammonium and facilitating the union of nitro en with h 'dro en or sub stances containing the same, by its contact action therewith, and further facilitating the union by assimilating or associating the mercury with calcium, palladium, etc., or similar metal having a natural aiiinity for hydrogen, thereby acting as an intermediary or carrier of hydrogen to the energized nitrogen.

'ln carrying out my invention for the production of ammonia l provide a receptacle containing mercury and subject it to rapid a itation by shaking or otherwise moving t e same, or the `mercury therein, and then introducing into or throu h the agitated mercury nitrogen and hy rogen, whereby the nitrogen is caused to combine or unite with the hydrogen in the resence of the mercury forming ammonia NH3), some of which, together With a portion of the iiydrogen, unites with the mercury producing ammonium amalgam, which may be finally recovered Vas ammonia by heating the amalgam so formed. By introducing the nitro` gen and hydrogen in a heated condition, either individually or collectively, the fory mation of ammonia is facilitated and the attained.

'It can be seen that the formation of ammonia from nitrogen and hydrogen can be continuously performed by passing a current of nitrogen and hydrogen throu h the agitated mercury, referablyA heate and the ammonia thus` ormed, collected or recovered byV passing the resultant gaseous product into or through an absorbent agent, such as water or preferably acidulated Water, such as dilute sulfuric or hydrochloric acid, in whichA case ammonium sulfate or chlorid is produced, or it may be secured in any other convenient manner.

Instead of passing the nitrogen and hydrogen through agitated mercury, I can atomize the mercury with a blast of compressed nitrogen and hydrogen or cause the substances to be rapidly associated or agitated in any convenient manner.

l find it of advantage to employ mercury containing calcium, Athe latter of which assists or acilitatesthe union of nitrogen and hydrogen by absorbing the hydrogen at ,ordinary temperatures, transiently forming intermediately, so called, calcium hydrid, which is broken up into ammonia by action of the nitrogen, which with hydrogen forming ammonium amalgam. Particles of metallic calcium, or so called calcium hydrid, may be employed instead of or Without mercury, but find the presence of mercury greatly advantageous, as it facilitates the action of the calcium or similar contact substance at ordinary temperatures and also prevents the action ofcalcium on the lining or Walls of the container, especially if it be i of glass'orenamel.

Exposing nitrogen and hydrogen to the action of agitated combining agents While under fessure also increases the yield of ammonia and is a preferred Way of introducing thegases.

Many other substances than mercu may be employed to induce the combination of nitrogen and hydrogen by agitation, attrition, or friction, such as sharp sand or silica, in which case it is preferable to hea-t the nitrogen and hydrogen and produce a sand blast by action of said heated gases under pressure; Iupon the subsidence ofv said hot blast the gases to a. large degree will be found to have combined, forming ammonia which can be absorbed, collected, or recovered in any convenient manner. I find it, however, of advantage to employ contact, agitating or rictional substances which have a natural aiinity for ammonium at low temperatureandifrom which it can be readily liberated by simply elevating the temperature, such as mercury or mercury and calcium.

ln employing mercury or amalgains as agitating or combining agents,.it is found that by passing a current of electricity through the metal during agitation with the nitrogen and hydrogen, that union and formation of ammonia is further facilitated by the numei'ous electric sparks produced by the rapid completing and breaking of the electric current circuit throughout the mass durinv agitation, which means is preferably empoyed for the additional feature of heating the mercury for liberating any ammonia which may with hydrogen have formed an amalgam during t-he progress of the process.

Instead of employing hydrogen per se,

substances containing the saine in a yielding or combining condition, such as methane, may be employed, in which case methyl ammonias may be produced, such as methyl-` amin, dimethylamin, triinetliylamin, or

methyl ,ammonium compounds or com ositionsmay be formed. lhe preferable orm of hydro en containing substance, suchA as methane,

eing natural gas which in some cases contains as high as ninety-six per cent.

o (96%) methane By employing such substances as methane or naturalgas, nitrogen may be. fixed in such a manner .as to form compounds or salts with suitable acids, which are valuable as fertilizing agents.

spirit of my invention.

Other alkyl hydrids may also be substituted for metlv hydrid (methane) producing correspon compounds, without epa'rting from the Instead vof agitating the mercury or other combining agent mechanically, it can be ngitated by forciiig a rapid'stream of nitrogen and hydrogen or other fluid or solid through or in contact with the salme.

Other hydrogen, or hydrogenlcarbon compounds, such as-'hydro-carbons, may be sub- `stituted for. alkyl hydrids or paraiin hydro-` carbons, such as olefins, acetylenes, etc., so

ioA

As a. concrete example of this process and the manner in which it is carried out in conjunction with the apparatus above described, the formation `of ammoniav from free nitrogen and hydrogen, through the mediation of mercury or Quicksilver will bc taken. Mercury is introduced into the vessel 1, through the opening 33, until it reaches ap roXiniately a level communicating with t ie reticulated pipe 27, at which time the opening is closed. The coil 2T, is brought into electrical communication with one terminal of a generator or other source of supply, not. shown. and the perforated, reticulated coillt, is brought into commu nication with the opposite terminal ot' said supply. A refrigerating fluid is then caused to circulate through the coil 2i'. by open! ing valves 28 and 29, for the purpose of refrigerating and maintaining the mercury, communicating therewith, at a temperature approximately sixty degrees F., or below, 'l'. e., ator below ordinary atmospheric teniperature. Nitrogen gas is then supplied through pipe 11, and hydrogen gas through pipe 12, by opening the respective. valves 13, said valves being so adjusted. with reference to the gas pi'essures, that a mixture of nitrogen and hydrogen, in lproportion approximately one of the former to four of the latter, by volume, is caused to be forced through the check-valve 22. into the vessel 1, through the perforations 15, at a pressure approximately fifty pounds, which pressure is ascertained by theV gage 20. As the mixture of nitrogen and hydrogen is introduced into vessel 1. the said vessel is caused to re- Avolve rapidly by means of the gearing, thereby causing the mercury therein to be rapidly tumbled` oscillated, and agitated in contact or in communication with the mix# ture of nitrogen and hydrogen, in such a manner that the frictional or attritinal ef- 1tertl thereof causes the nitrogen and hydrogen to combine. and in the presence of an excess of hydrogen, to temporarily unite with the mercury, producing so called ainnio'nium amalgam; the combining of the nitrogen and hydrogen, in the presence of mercury, being augmented by the action of electricity passing between the coils 27 and 14. in a rapidly interrupted manner, by the action of the falling, (lashing, or agitated particles of mercury assing through or between the ixed coils in the revolving lvessel 1. The mixture of nitrogen and hydrogen is continually and gradually forced into the revolving vessel in order to maintain a pressure therein of approximately sixty pounds, in order to compensate for the condensation and absorption occurring in said vessel during the forn'iation of ammoniacal substances,

and absorption or union of the same with or by `the mercury, The nitrogen and hydrogen is supplied to the apparatus yin the. opening 4t), into the chamber 2. froml which it is discharged through the pipe or duct 18 and 16. on opening the valve 17, and from thence conveyed to a suitable reservoir. or absorbing" or combining chamber, not shown. and after the separation of the ammonia from the associated hydrogen, they said hydrogen may be recovered in any convenient manner for future use After exposing the substance in vessel 1, to the action of heat and electricity, `during this second stage of the process for about one hour, the larger portion of the available ainiuoiiia will be found to have been discharged, atwhich time the valve 17, is closed, the steam discharged from coil 27, the revolution of the apparatus stopped. and the contents of the vessel 1. cooled by again passing the refrigerating Huid through coil 2T. Vt'hcii the. temperature of the mercury in vessel 1. has been reduced. by thus cooling, to a temperature approximately.sixty degrees F.. or below. more nitrogen and hydrogen is introduced by opening valves 13, the vessel 1, revolved and the process continued as before.

lt is found advantageous to add to, or amal-v gamate with the mercury certain substances of so called contact or catalytic nature. capable of facilitating the union of nitrogen and hydrogen to form or produce ammonia., or transiently ammonium amalgam. such as calcium. ily liquefying metal, such as calcium at ordinary temperatures, having in a. heated state an afiinity for nitrogen or hydrogen, or both, by the action of tinid solvents or liquefying agents. such as mercury. the aftinity of said metal for nitrogen, hydrogen. or both. is induced, under ordinary atmospheric conditions of temperature. Without the necessity of licatingtlie same; furthermore, such calcium. or similar substance', acts as a so called catalytic or contact agenti in the icorniation of ammonia from free nitrogen and hydrogen in the presence of an agent ot solvent combining or assiinilating nat ure, such as mercury, with which it orms an amalgam, together with hydrogen, and from which it, can he finally eliminated by dissociation or decomposing the amalgam by the action of heat.

Such metals as calcium having an anity, in a heated-state, for nitrogen, hydrogen. or both. when liqueed by the action of other substances, at ordinarytemperatures,

and especially when associated with sub-- stances capable of uniting with compounds of nitrogen and hydrogen, such as mercury, in the formation of mercury amalgam, are

found to act with superior avidity in thefixation of nitrogen and hydrogen, and formation of compounds or compositions there- .of, without thel assistance of hcat'froin an extraneous or other source, than is attained or obtained by the employment of such substances per se iii a heated slate.

By substituting alkyl hydrids, such as methane` or other hydro-cai'bons containing y hydrogen in a form available for the formation of alkyl aniinon'ias, or ammonium bases, for hydrogen per se, as introduced into the apparatus through pipe 12, alkyl aininfniia, or ammonium bases, may be produced in the performance of the process described, in`

place of ammonia per se, as obtained when free hydrogen only is employed.

vIn subjecting the substances employed iii the formation of ammonia, alkyl ammonia, or ammonium bases, to the action of electricityl do not desire to confine myself to any particular forni or character of electricity, but intend to include any and all character or forms which may be selectively adaptable to any particular case, or the production of any particular product, be it a frictioiial, pulsating, alternating, polypliase, of high or low tension,` or. otherwise. Neither do I desire to confine myself to the formation of ammonia, or alkyl aininonias, but intend to include and do include the4 4application of the herein described process for the fixation of nitrogen with hydrogen per se, or hydrogen compounds or coinpositions be they of aminoiiiacal, azoical, diazoical, or other form or character of nitrogen-hydrogen containing compounds, be they simple, compound, complex, or polymeric in nature, or in which the nitrogen may exist yin combination at any possible atomicity.

The hydrogen, or substances containing the same in a yielding or combining condition, may be employed per se, or associated with other substances such'as may be found in nature, in the performance of this process for the making of nitrogen-hydrogen conipounds, Without departing from the spirit or scope of my invention, such, for instance, as the Iemployment of natural gas which largely consists of alkyl-hydrids, such as methylhydrid, (methane), ethylhydrid,

' (ethane,) etc., in the production of corresponding compounds, composite, or comlex alkyl ammonias of whatsoeverv nature, Ee they amin, amid,- imid, or otherwise.

rI`he terms ammoniacal and ammonia employed herein, with reference to substances capable of uniting therewith, have reference to hydrogen ammonid, or socalled ammoniuim (NIL), as well as am-v monia per se, and the' designation of substances associated therewith, with Whicli it will combine, to elements, compounds or compositions, such, for instance, as mercury and hydrogen, as a substance capable of uniting with ammonia, forming mercuryliydrogen ainnioiiid, or ammonium amalgam.`

The formation of ammoniacall compounds or compositions, in acordance with this process, may be carried on under reduced, or in-n Without departing from the spirit or scope of my invention.

It should be noted't'hat an 4atmosphere of hydrogen containing nitrogen enough to form ammonium, is of such low density as to be looked u on, or produce a condition which ordinari y results, when mercury is agitated in rareed atmosphere, when such mercury is agitated with the lighter gases, such as nitrogen containing hydrogen largely in excessof volume, such as four volumes of hydrogen to one of nitrogen.

Instead of employing mercury, which is iuid at ordinary temperature, as a medium for supplying energy and formin compounds containin nitrogen and hy rogen, I can employ mo ten metals, such as lead, or alloys of selective meltingv point, such as .fusible metal, without departing from the spirit or scope of my invention.

I have found it of advantage to augment the process of syntheticallyr formin nitrogen hydrogen containing compoun s from their elements, or substances containing the same in a yielding condition, as hereinbefore described, by exposing the combining or reacting substances to, or associating the same with, water, either as liquid vapor or steam, or under conditions capable of producing a like state, whereby the formation or union of the nitrogen-hydrogen-containing compound or compounds, in, with, or through the associated combinabletluid, and its dissociation and decomposition, or evolution, \is enhanced, and its recover in affree,

neutralizing agents may beta ka ine in some i cases, where the nitrogen-hydrogen-containin compound obtained is of more or less acid character, such as azoic, hydrceyanic acid, etc. y
